关于[Ln(XM_(11)O_(39))_2]~(n-)类配合物合成有一些报道,但它们均未指出其中配体及所得配合物的构型,本文以α-和β_2-SiW_(11)O_(39)~(8-)为配体,首次合成了双-(11-钨硅酸根)合镧系元素钾盐的异构体并进行了结构表征。 1 实验部分 1.1 仪器和试剂 pHS-2型酸度计;883型笔录式极谱仪,384B型极谱分析仪,阿尔法
There are some reports on the synthesis of [Ln (XM_ (11) O_ (39)) _2] ~ (n-) complexes, but none of them indicate the configuration of the ligands and the resulting complexes. (11) O_ (39) ~ (8-) as ligand, the isomers of lanthanide potassium salt of bis- (11-tungstosilicate) were synthesized and characterized. 1 Experimental 1.1 Instruments and Reagents pHS-2 pH Meter; 883 Transcriptional Polarography, 384B Polarographic Analyzer, Alpha
